Biography

Andrew Hearin is a member of the Cosmological Physics & Advanced Computing group in the High Energy Physics Division at Argonne National Laboratory. After receiving his PhD in 2012 from the University of Pittsburgh, Hearin worked as a postdoc in the Theoretical Astrophysics group at Fermi National Lab, and then as the Yale Center for Astronomy & Astrophysics Prize Postdoctoral Fellow. He joined Argonne as an assistant physicist in 2017.

Hearin’s research interests span a range of problems in cosmology and galaxy formation physics. He studies cosmological structure growth in the nonlinear régime using forward-modeling techniques and large-volume simulations. He is the lead developer of Halotools, an open-source python package for modeling the galaxy-halo connection. Hearin is an active member of numerous ongoing and near-future galaxy surveys such as the Dark Energy Science Collaboration in the Large Synoptic Survey Telescope (LSST-DESC), and the Dark Energy Spectroscopic Instrument (DESI). Much of Hearin’s research focuses on utilizing high-precision measurements from these surveys to understand the physics that shapes galaxy formation, and to uncover the physical nature of dark matter and dark energy.
